The Browns signed defensive back Tigie Sankoh, a native of London, England. Sankoh played amateur football and attended the American Football Academy in Bristol before playing for the London Warriors in the British American Football League. He was assigned to the Browns through the NFL's International Development Program. He will not count against the roster until final cutdown. The team also signed quarterback Brogan Roback, who set records for passing touchdowns and total offense at Eastern Michigan.
